I can see Mr. Burns, like ~1r-R said, but the first person I thought of (almost immediately) was James Woods. And then from there I started thinking of Hades from Disney's Hercules and of course both of them being evil... it seemed fitting. Excellent work. I just came from your "Broly the Super Saiyan' work and found that astounding, prompting me to view the rest of your DB gallery. All of your work is great, but I'm a DB nut. Major kudos. My gf says I should post my old works and/or get back into drawing, but I'm so out of practice. I will say that seeing your work has given me some inspiration to pick the pencil back up. Thanks for that.

side-note: I was just thinking... it's truly amazing how much power was inside this little alien at the time. I know as the show went on his power became negligent, but I still believe he was the best DBZ villain and Goku's fiercest adversary.
